Accept no substitutes! All Roofmaster Hoisting Wheels feature the highest quality die-cast aluminum wheels. These wheels are made in the U.S.A.  Incorporate that with maintenance-free bearings, plus an all-steel framework.  You can tap the wheel and it has a ring, not like imported or yellow imitation "sand casted" wheels that will break if dropped. 

Roofmaster ladder-mounted hoisting wheels are designed to stay in place on any two rungs of a ladder without swaying or wobbling. The handle is 24" from the ladder mounting point for extra clearance for bigger, bulkier lifts. Use with 3/4" rope only. This is to be used on a "D" Rung Ladder (usually aluminum or fiberglass)
